When inserting glass tubing, why is it important that you wear safety goggles and gloves and that you cover the tubing and stopper with protective pads of cloth?

It is important to wear safety goggles and gloves or cover the tubing with the stopper or protective pads of cloths because it is a way of protecting one’s self in exposure with the chemical or fluid that is placed inside the glass tubing. The chemicals placed inside could be toxic and could be harmful for an individual and could cause explosion if the chemical is hazardous and it is not done right.
